I was trying to learn Entity Framework and SQLite using this tutorial. However, I get an error. The error thrown is: An unhandled exception of type 'System.TypeInitializationException' occurred in EntityFramework.dll Additional information: The type initializer for 'System.Data.Entity.Internal.AppConfig' threw an exception.
